Process for preparing a sintered steel powder article |
| 摘要 |
<p>Steel powder containing chromium, molybdenum and vanadium is pressed in a die into raw powder blanks by hot pressing at 130-150 [deg]C and at least of 750 MPa, giving a density of at least 7.2 g/cm3>. The blanks are sintered at 1150-1300 [deg]C. This is followed by hot isostatic pressing to give at least 99 % density.</p> |
